Solid component
Works as expected. The reed switch is encased well. Just wish the jumper wires were a bit longer for my setup.

Easy for beginners
Clear labeling on the pins. VCC, GND, and OUT. No confusion. Highly recommend for starters learning about sensors.

Great for Arduino Projects
Works perfectly with my Arduino Uno. Very sensitive to the included magnet. Easy to wire up with clear pin labels.

Good value for money
Bought these for a DIY home security system. They work well, though the magnet needs to be quite close to trigger reliably.
